How is the 'Total Scheduled' time calculated for a service resource in the Salesforce Field Service Dispatcher Console?

The Total Scheduled field under resource utilization in the Dispatcher Console calculates the duration of a Service Appointment by measuring the time between the appointment's start and end time — without filtering by the Operating Hours configured for the resource.
When a multi-day Service Appointment is scheduled, the resource utilization for the Service Resource will include off-hours (e.g., nights, weekends) in the total calculated duration, rather than only counting business hours within that window.

Example: If a Service Appointment spans from Monday 9 AM to Wednesday 5 PM, the Total Scheduled value will include all hours in between — including overnight non-business hours — rather than only the working hours within that window.

Steps to Reproduce

1. Create a multi-day Service Appointment spanning across 2 or more days.
2. Schedule the appointment to a Service Resource in the Dispatcher Console.
3. Observe the Total Scheduled value under resource utilization for the Service Resource.
4. Note that the value includes time outside of the resource's configured Operating Hours.
